PROTECTOR FOR CURTAINS Filed Feb. 13, 1928 anvento'c Patented May 13, 1930 PATENT OFFICE ARTHUR STANLEY DAVIES, OF CLEVELAND, OHIO PROTECTOR FOR CURTAINS Application filed February 13, 1928.

My invention relates to protector means generally and more particularly to means for protecting rollable or rolled objects and still more particularly to means for protecting rollable curtains and permitting the same to be unwound without disturbing the protecting means.

One object of my invention is to provide a simple, inexpensive, and effective means to 0 protect curtains against the accumulation of dust thereon. Another object is to provide a means on the protector to permit the same to be readily supported on the brackets which support the curtain. Another object is to provide a longitudinally adjustable protector so that the same is readily adaptable to diiferent widths of curtains or different spacing of brackets which support the curtain. Another object is to provide a stiffening means for the protector so that the same can be made of light weight material and yet be sufficiently stiif to remain in position. Another object is to provide a guide means between relatively movable members of the protector.

Other objects will appear, or become apparent or obvious, or will suggest themselves, upon an inspection of the accompanying drawing and the following description of the device shown in this drawing.

In curtains, such as rollable Window shades for instance, dust or other foreign matter collects on the tops of the same, particularly when the shade is not frequently wound on or from the roller. In time this dust adheres tightly to the curtain and must eventually be removed by a cleaning process which invariably removes some of the color of the curtain and thereby causes spots or streaks to appear on the curtain where the dust has been cleaned ofi.

My invention aims to provide the necessary means to prevent the accumulation of dust on curtains and thereby eliminate the necessity of cleaning the curtain and the consequent discoloration of the same.

In the accompanying drawing Fig. 1 is a general perspective view of a protector for a rollable curtain embodying my invention.

Fig. 2 is an end view of Fig. 1 taken at X.

Serial No. 254,034.

Fig. 3 is a transverse section, on a larger scale, taken in a plane indicated by the line 3-3 in Fig. 1 to show the relations bet-ween the two parts more clearly.

Fig. 4 is an end view of Fig. 1 showing a modification of the supporting means for the protector.

In the device shown in the drawing The member or part A, forms one member of a pair of members, and is formed of one sheet of material bent into a substantially spiral form oross-sectionally to provide the opening 10 and into the bead 11 on the inner longitudinal edge thereof and-thebead 12 on the outer edge thereof. One end of the member A is closedby the wall 13 which has the opening 14 through the same to fit over the nose 15 on the bracket 16 (shown in dotted lines) and thereby support the outer end of the member A on the bracket 16 without screw or other fastening or supporting means.

The member or part B, forms the other member of a pair of members, is formed of one sheet of material, bent into a substantially spiral form cross-sectionally to provide the opening 17 and into the head 18 on the inner longitudinal edge thereof. The member A is diametrically smaller than the member 13, the bead 11 smaller than the bead v 18, and the bead 12 is smaller than the head 19 so that the parts of the member A can tclescope into the corresponding parts of the member B as clearly seen in Fig. 3.

One end of the member B is closedbythe wall 20 which has the opening 21 through the same to fit over'the nose 22 on the bracket 23 (shown in dotted lines) and thereby supports the outer end of member 13 on the bracket 23 without screw or other fastening or supporting means.

The lip 24 in Fig. 2 is provided on the .wall 20 to engage the slot-25 in the bracket 23 to prevent rotation of the protector.

VVhenthe protector is not supportable on the noses of the brackets, the .walls on the ends of-the members A and B can be provided with rectangular openings 26 shown in Fig. 4 to*fit over flange parts of the'brackets equivalent of-the nose 22 and thereby support 5. tain.

The members A and B are telescopable so that the protector as a whole can be lengthened or shortened within the capacity thereof and thereby permits the protector to be used for a variety of diliercnt widths of curtains or different spacings of the brackets.

The rollable shade or curtain can be installed in the usual manner. The protector is placed or telescoped over the rolled up portion of the curtain with the free end thereof extending through the openings 14 and 17; and the members A and B re telescoped sutfiriently far to expose the bearing pins on the curtain, the roller is then inserted into the brackets in the usual manner; the members A and B are then distended so that the holes in the end walls thereof are telescoped over the corresponding noses of the brackets whereupon the entire device is ready for oporation.

The beads form stiffening means for the members A and B as well as guide means between these members to prevent rotation of one member 1n relation to the other and l to stifien the protector as a whole.

My invention protects the curtain against dust and thereby eliminates the necessity of cleaning accumulated dust from curtains and also eliminates discoloration of curtains.

I am aware that my invention is applicable to devices other than the one shown and described and selected to illustrate my invention but not to limit the same and that changes can be made in the structure as well as in the arrangement of the elements shown and described within the scope of the appended claims; therefore without limiting myself to the precise application of my invention nor to the precise structure and arrangement of elements as shown and described.

I claim 1. A protector for a rollable curtain including a pair of longitudinally telescopable members of substantially spiral form crosssectionally and an apron formed on the outer end of each of said members extending downwardly further than the usual spiral to outwardly confine the curtain.

2. A protector for a rollable curtain including a pair of longitudinally telescopable members of substantially spiral form crosssectionally; an apron formed on the outer end of each of said members extending down- I wardly further than the usual spiral to outwardly confine the curtain, and beads formed on both longitudinal edges of each of said members to stiffen the protector.

3. A protector for a rollable curtain including a pair of longitudinally telescopable members of substantially spiral form crosssectionally; an apron formed on the outer end of each of said members extending downwardly further than the usual spiral to outwardly confine the curtain, and telescopable beads formed on both longitudinal edges of each of said members to guide said members in relation to each other and to stiffen the protector.

A. A curtain protector having two members in telescopic relation with each other, each of t said members supportable on one of a pair of positionally fixed spaced brackets supporting a removable curtain roll each of sai members being of substantially spiral form cross-sectionally and open at an apron formed on one side, one edge of each of said members, beads formed on both longitudinal edges of both of said members, the beads on one of said members in telescopic relation with the beads on the other one of said members and R an end wall on each of said members and having means to engage the corresponding one of. said brackets.

5. A protector for a rollable curtain in cluding a pair of longitudinally telescopable members of arcuate form cross-sectionally, an apron formed on the outer edge of each of said members and extending downwardly and inclined inwardly of the protector to confine the curtain outwardly, and a lead formed on the inner edge of each of said members and spaced inwardly of said apron and extending upwardly of the protector to confine the curtain inwardly of the protector.

6. A protector for a rollable curtain including a pair of longitudinally telescopable members of arcuate form cross sectionally, an apron formed on the outer edge of each of said members and extending downwardly and inclined inwardly of the protector to confine the curtain outwardly, a lead formed on the inner edge of each of said members and spaced inwardly of said apron and upwardly of the protector to confine the curtain inwardly, and telescopable beads on the outer edges of said aprons and on the outer edges of said leads to stiffen the protector and to guide said members in relation to each other.

In testimony of the foregoing I affix my signature.

ARTHUR STANLEY DAVIES.
